Definitions

  • the present invention aims to provide a combustion method with high combustion efficiency by supplying incinerated ash and water during combustion of combustibles. More specifically, as a combustion method suitable for use in high-temperature combustion mechanisms, industrial waste incinerators, and other incinerators, water is supplied together with incineration ash during combustion to achieve higher temperature and shorter time. It embodies a combustion method that improves combustion efficiency, such as complete combustion.
  • combustion efficiency can be reduced by measures such as lowering the sulfur of the fuel, flue gas desulfurization, flue gas denitrification, or selecting the composition of gasoline / light oil as the fuel. I have tried to raise it.
  • gaseous fuel it is important to maintain stable combustion without lowering this state because it is inherently highly efficient combustion. In order to achieve stable combustion, methods such as adjusting the mixing ratio of air and combustion, fire temperature, emissivity, cleanliness, and the length of fire, etc., and reducing heat loss as much as possible have been adopted.

Abstract

L'invention concerne un procédé de combustion utilisant de l'eau. Ce procédé se caractérise en ce que de l'eau ou de la vapeur est mise en contact avec une cendre d'incinération contenant de l'aluminium dans une zone de réduction de zones de réduction et d'oxydation formées pendant la combustion de matières combustibles, d'où la production d'un gaz combustible et l'obtention d'une efficacité de combustion améliorée. Ce procédé comprend un procédé de combustion présentant une efficacité élevée et consistant à acheminer une cendre d'incinération et de l'eau dans une flamme formée par combustion de matières combustibles.
